Modernizing the Backbone of State-Wide Insurance

Impact Summary

• Platform Modernization: Working on upgrading legacy Guidewire v9 to a scalable Cloud environment.
• API Performance Gains: Upgraded over 50 APIs to Java 17 and Mule 4.9 for superior processing.
• Geospatial Accuracy: Standardized all address data through the NSWPoint State Address Search.
• Infrastructure Optimization: Reduced maintenance overhead by transitioning to a cloud-first strategy.
• Risk Mitigation: Executed zero-downtime deployments for massive runtime upgrades.

Client Overview

A leading public insurance and care provider in New South Wales reached a stage where their aging on-premise infrastructure could no longer support the rapid pace of modern digital service requirements. Operating as a statutory corporation, this entity serves as the backbone of social and economic well-being in Australia. 

The reliance on third-party address providers and an outdated MuleSoft runtime created security vulnerabilities and slowed down critical updates. In response, a massive, large-scale modernization program to upgrade the MuleSoft integration platform, migrating Mule applications to the latest Mule runtime and enhancing scalability, security, and operational efficiency. By upgrading 594 endpoints to the latest standards, the organization shifted from a reactive maintenance posture to a proactive digital-first strategy. Today, the organization utilizes a resilient, highly available platform that aligns perfectly with whole-of-government standards, ensuring long-term sustainability for the state’s most vital insurance schemes.

Technical Challenges

Infrastructure Rigidity

The legacy Guidewire v9 implementation was restricted by on-premise hardware, making it difficult to scale during periods of high claim activity. This lack of flexibility hindered the organization’s ability to deploy new features or respond to regulatory changes quickly.

Integration Debt and Compatibility

With over 52 APIs running on an older MuleSoft version, the organization faced performance bottlenecks and security risks. Many connectors were becoming obsolete, necessitating a complete review of API policies and runtime configurations to ensure continued compatibility.

Data Inconsistency in Location Services

The previous reliance on external address search providers led to inconsistent data quality. This created errors in policy underwriting and claim tracking, as address information did not always align with authoritative government standards.

The Solution

Seamless Guidewire Cloud Migration

The team is working on moving the current Guidewire v9 environment to the Guidewire Cloud platform. This move removed infrastructure maintenance work and provided an environment that supports faster updates, improved security, and better operational stability.

Enterprise-Wide MuleSoft Runtime Upgrade

To prepare the integration layer for the future, the team updated the MuleSoft runtime to version 4.9 and moved to Java 17. This work included reviewing more than 594 integrations, updating supported connectors, and updating API policies to meet the latest compliance standards.

Authoritative Address Integration

By connecting the NSWPoint State Address Search service, the team replaced multiple external data sources with a single, trusted source. This upgrade ensures that all address data is accurate, consistent, and fully aligned with state government standards.

Business Results

Enhanced Financial and Operational Stability

The successful management of the Treasury Managed Fund’s integrations with external providers has improved the financial stability of the scheme. Operations are now more seamless, allowing for better risk coverage for government agencies.

Drastic Reduction in Downtime

Through the design and execution of robust deployment and rollback strategies, the massive MuleSoft upgrade was completed with minimal disruption to business operations. This ensures that essential services remain available to the public without interruption.

Improved Security and Compliance

The adoption of a cloud-based strategy and the latest MuleSoft policies has significantly improved the company’s security posture. The team is now better prepared to handle sensitive data while meeting changing regulatory requirements.

Looking Ahead

With the move to Guidewire Cloud and the latest MuleSoft runtime, the organization has created a flexible foundation for future innovation. The next phase involves looking at AI-driven integration patterns to automate more claim triage processes and speed up care delivery for people with serious injuries.
